GARBAGE AND REFUSE INCINEBATOB.

' Application filed January 8, 1923. semi m. 811,364.

To all whom it may concern:

Be it known that Pmn W. Tnnmonx and CARL BARKJIAUSEN, citizens of theUnited States, residin at Milwaukee, county of 5 Milwaukee, anc l Stateof Wisconsin, have invented new and useful Improvements in Garbage andRefuse Incinerators, of which the following is a specification. Ourinvention relates to improvements in 1 garbage and refuse incinerators.

The object of our invention is to provide an improved incinerator whichwill be odorless and which is capable of utilizing as fuel, oil, coaldust or wood; also to provide an I automatic system for preh ating thegarbage or other refuse, feeding it into the combustion chamber,withdrawing unburned gases from above the material and feeding suchgases through the fire, whereby the obnox ions gases may be whollyconsumed and the products of combustion finally delivered through thestack in a substantially odorless condition.

In the drawings":-- v Figure 1 is a vertical sectional view of animproved incinerator embodying the invention, the section being drawn toa plane which includes the axes of the return flues for burning thegases.

Fi ure 2 is asectional view at right angles to Fig. 1-drawn on line 2--2of Fig. 1.

Figure 3 is a sectional view drawn on line 3-3 of Fig. 2.

Figure 4 is a sectional view drawn on line 4-4 of Fig. 2. A

Like parts are identified by the same reference characters throughoutthe several views. I

In the drawings, A indicates sliding doors through which the material isdelivered to the incinerator into hoppers B.

G are ducts for the return of gases to the fire, D are grates disposedbetween the upper and lower marginsof the hopper and inclined downwardlytoward the walls B to form' upper and lower portions of the hopper, Eare inclined grates and F are dumping grates. G is a conveyor for theashes and incombustible material dropping from the combustion chamber H.I is the chimney to which communication is had through. the openings Iand I".

The walls B .of the hoppers Bsubdivide the hopper space into 'twosections. The material, as it dries and bakesinthe hopper sections,slides down along the walls B until 1t passes the grates D, whereupon itdrops upon the auxiliary grates D' which are adapted to tilt and deliverthe material into the fire-pot and. indirectly the grates D assist insuch regulation .by directing the materials toward the inclined walls B.

The ducts are equipped with suction fans for positively withdrawing thegases from the upper portion of the hopper chamberand delivering theminto the ash-pit un- =derneath the fire-pot, i. e., underneath thegratesE. Such fansare indicated at K.

The blast of air and gas delivered by the fans through the horizontalruns C of the ducts G produces an aspirating-efi'ect in the. auxiliaryducts C" which take the gases from beneath the inclined grates D. Thisaspirating efl'ect-is increased by baflies L which extend obliquely fromone side parti'ally across'the lower end of each of the ducts C. Y

The heat of the fire in the combustion chamber H is relied upon to dryout the material in the hoppers B. The material in so the lower portionof. the hoppers between the inclined grates D andthe tilting grates Dbecomes very thoroughly dried. The walls B define a closed hot chamberabove "the arch I this chamber having no inlet and i the chimney outletI" being intended merely to relieve the chamber. from internal ressuredue to heat; Therefore, the wa B may be raised to such a temperaturethat I material falling thereon isvery rapidly dried and brought intocondition for burn ing and as this material passes most readilydownwardly'to the portion of the'hopper below the grates D, the othermaterials are directed by said inclined these hot walls B so thatsubstantially all material is brought into contact with or. closeproximity to said walls before reaching the fire-pot. Y

To support combustion in the fire-pot the grates D toward" fuel isdelivered thereto under air pressure.

It is, therefore, possible to use oil, or other liquid fuel, or to usesolid fuel which, if desired, may be'in .finely subdivided form.

We claim: 3 1. In a garbage incinerator, the combination with afire-pot, of, a superposed receiving hopper having an inclined wall anda co-operating'wall, said inclined wall being inclined downwardly towardsaid co-operating wall, and a grate downwardly and inwardly inclinedfrom the co-operating wall toward the inclined wall intermediate theupper and lower margins of said hopper,

- inclined hot a through which material may be'delivered into thehopper, tilting grates disp0'sed between the margins o'f'said arch andsaid tions and'inclined inwardly from the in-' thereby to subdivide saidhopper into upper and lower portions. 7

2. In a garbage incinerator the combinationwith a fire-pot, of asuperposed receiv-c ing hopper having inner walls downwardly andoutwardly inclined and outer walls, and grates downwardly andinwardlyinclined from the outer walls of the hopper toward said inner walls atpoints between their upper and lower margins, said grates partiallysubdividing the hopper intoupper and lower portions. 1

'3. In a garbage incinerator, the combination with a fire-pot, ofasuperposed receiving hopper having inner wallsdownwardly and outwardlyinclined and outer walls, and grates downwardly and inwardly inclinedfrom the outer walls of the hopper .toward intermediate portions of theinner walls, said grates partially subdividing the hopper into upper andlower portions, and

inclosing walls, said grates vbeing adapted in one position to su portmaterial in the path of the flame an gases of combustion coming from thefire-pot and adapted in another position 'to permit such material- 7 topass from the hopper into the fire-pot,

and co-o rating grates partially subdividingthe opper into upper andlower secclosing walls to thereby direct material from the upper sectionto the lower section along the surfaces of said inclined hot plates andaway from said inclosing walls.-

5. In a garbage incinerator thecombin'ation of'an enclosing chamberprovided with a- "grated fire-pot m its'lower portion, a

superposed arch spaced from.walls of the enclosing chamber at therespective sides H of the arch, tilting grates insaid spaces 2 adaptedto regulate deliveryof material to the fire-pot from the space above thegrates, upwardly convergin hot plates above the arch, and means materialfrom the upper portion of the chamber inwardly and downwardly towardsaid hot plates, whereby such material is caused to slide downwardlyalong the hot plates to; said gratesv 6. Ina garbage incinerator thecombination of an enclosing chamber provided with. v r a grated fire potin its lower portion, a

superposed arch spaced from.walls ofthe enclosing chamber at therespective sides or delivering of the arch, tilting grates in saidspaces adapted to regulate delivery of material to the fire-pot from thespace above the grates,

upwardly converging hot plates above the arch, means fordeliveringmaterial into the upper portion ofthe chamber downwardly uponand along said hot plates to said grates, and a set of feed regulatinggrates controlling the downward movement of material along. said hotplates.

7. In a garbage incinerator the combination of an enclosing'chamberprovided with a grated fire-potin its lower portion, a-

superposed arch spaced from walls ofthe, enclosing chamber atvtherespective sides of the arch, tilting grates in .said spaces adapted toregulate delivery of material to the fire-pot from the space above thegrates, I

upwardly converging hot "plates'flabove the arch, and means fordelivering material into the upper portion of the chamber down- I wardlyupon and along said hot plates to said grates, and aset of feedregulating grates controlling the downward movement of material alongsaid hot plates, said. enclosing chamber walls being provided with ductsleading from theupper portions of the chamber downwardly topointsbeneath the fire-pot, whereby gases of combustion maypaseEthrough thematerial above the tilting grates and then downwardly with vapors fromsuch material to be delivered through the fire from below.

. 8. In a garbage incinerator a chamber subdivided by into an uppermaterial receiving hopper section, a lower material supporting hoppersection, a fire-pot, and an ash pit having ducts leading,'respect-ively,from both hopper sections to the ash-pit, and power partition walls andgratings driven means for maintaining a forced cirthe 7 material in thehopper sections and. downwardly in said ducts. ,1
